Abstract: Described herein is a method for electrostatic printing comprising: (i) providing an ink composition comprising: a hydrocarbon carrier liquid and particles comprising a resin and a colorant, and wherein the ink composition contains less than 0.3 mg of charge director per g of solids in the ink composition; (ii) adding a charge director to the ink composition, such that the total amount of charge director in the ink composition is at least 0.6 mg per g of solids in the ink composition, and, (iii) within a predetermined time of adding the charge director, printing the ink onto a print medium in an electrostatic printing process, wherein the predetermined time is 90 minutes or less. Also described herein is a packaged ink composition, and method for producing it.
